Allows you to enable encryption of cache values with:
```yaml
\# config/solid_cache.yml
production:
encrypt: true
```
or
```ruby
\# application.rb
config.solid_cache.encrypt = true
```
Requires Active Record Encryption to be configured already.
Solid Cache by default uses a custom encryptor and message serializer
that are optimised for it.
Firstly it disabled compression with the encryptor
`ActiveRecord::Encryption::Encryptor.new(compress: false)` - the cache
already compresses the data.
Secondly it uses `ActiveRecord::Encryption::MessagePackMessageSerializer.new`
as the serializer. This serializer can only be used for binary columns,
but can store about 40% more data than the standard serializer.
Or allow custom context properties to be set:
```ruby
\# application.rb
config.solid_cache.encryption_context_properties = {
encryptor: ActiveRecord::Encryption::Encryptor.new,
message_serializer: ActiveRecord::Encryption::MessageSerializer.new
}
```
Add 170 bytes to the estimated size of each entry when encryption is enabled. This assumes that the default context properties are used.

This will need to wait for Rails to support binary encrypted columns - see rails/rails#52650.
